Bottle Closure With One-Piece Wire Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle closures are expensive to produce, consume high amounts of material, and are difficult to manufacture, with complications in maintaining a secure and user-friendly design, particularly due to the need for complex tools and high material costs.
Innovation Solution
A bottle closure system using a one-piece fastener with a through bore and a fastening element that engages with retaining structures on the bottle, featuring a design with a first region perpendicular to the bottle axis and a second region parallel to it, allowing for easy opening and closing without joints or levers, and incorporating an elastic seal for a secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional swing-top closures with two-part bails are used, then the closure can be opened and closed, but the device complexity increases and material consumption increases
Solution Approach 1:
The closure system is divided into functional segments: the closure body with integrated fastening element, the seal, and the retaining structures on the bottle. This segmentation allows each component to be optimized independently while simplifying the overall structure compared to traditional two-part bails.
Solution Approach 2:
The fastening element is merged with the closure body as an integrated component, eliminating the need for separate bail wires and complex assembly mechanisms. The first region and second region of the fastening element work together as a unified structure to achieve both sealing and locking functions.
2Reliability
If conventional swing-top closures are used, then the closure can be secured to the bottle, but the material costs increase
Solution Approach 1:
The invention extracts the essential security function from the complex traditional bail structure and implements it through a simplified fastening element with specific geometric features (first region perpendicular to axis, second region parallel to axis) that engages with minimal material in the retaining structures.
Solution Approach 2:
The fastening element's geometry is optimized with specific parameter relationships: the first region extends perpendicular to the bottle axis for engagement, while the second region extends parallel to the axis for structural support. This parameter optimization achieves secure fastening with reduced material volume.
3Ease of manufacture
If Kneipp holes are created in the mold parting area, then the closure can be attached to the bottle, but the manufacturing complexity increases
Solution Approach 1:
The retaining structures are pre-formed as integral parts of the bottle during the molding process, eliminating the need for subsequent Kneipp hole creation or post-molding modifications. This preliminary integration simplifies the overall manufacturing workflow.
4Adaptability or versatility
If wire bail closures with lateral grooves are used, then the closure can be detached and reattached, but the risk of unintentional detachment increases
Solution Approach 1:
The fastening element is designed with dynamic engagement characteristics: it can be easily inserted into the retaining structures during intentional opening/closing operations, while the geometric interlocking provides passive resistance against unintentional detachment forces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces material costs, simplifies production, and provides a secure, user-friendly closure that is easy to open and close, while minimizing the risk of unintentional opening and optimizing heat dissipation and structural integrity.
Implementation Method 1
The closure body can include an elastic seal, such as a rubber seal or a TPE seal, by means of which a sealing contact with a bottle mouth can be created.
